20 Kurus - Abdülmecid I Lambeth London Copper Sample

This piece is a pattern or sample struck in copper by a London manufacturer — almost certainly produced speculatively or as a commercial proposal for the Ottoman mint reform program of the Tanzimat period. The reference X# designation confirms it circulated outside official Ottoman coinage and was never adopted for currency use. Whether it was submitted in response to a specific tender or produced as a trade sample by a Lambeth die-sinker remains unresolved.
